Sessions

So you heard about the new spatial functionality in SQL Server 2008, rushed back to your database and added geography and geometry columns to all your tables, eager to create the next Google Earth-beating application. You then click the Execute button and wait.
And wait.
And wait some more. (You get the idea).
Spatial data is a rather unique beast, and designing efficient spatial queries requires specific techniques when compared to other, more traditional types of data.
In this session, we look at how the SQL Server database engine satisfies spatial queries, the theory behind spatial indexes, demonstrate the effects of altering the bounding box, use the spatial system DMVs and stored procedures to your spatial database

SQL Server spatial features have not yet made it into mainstream usage and many developers still ask "But *why* would I use them?". In this session, I hope to answer that question by replicating the functionality of Google Maps using only SQL Server.
